Bibliotheca (Photius) in the context of Patriarch Photius I of Constantinople

Five ancient Greek novels or ancient Greek romances survive complete from antiquity: Chariton's Callirhoe (mid 1st century), Achilles Tatius' Leucippe and Clitophon (early 2nd century), Longus' Daphnis and Chloe (2nd century), Xenophon of Ephesus' Ephesian Tale (late 2nd century), and Heliodorus of Emesa's Aethiopica (3rd century). There are also numerous fragments preserved on papyrus or in quotations, and summaries in Bibliotheca by Photius, a 9th-century Ecumenical Patriarch. The titles of over twenty such ancient Greek romance novels are known, but most of them have only survived in an incomplete, fragmentary form. The unattributed Metiochus and Parthenope may be preserved by what appears to be a faithful Persian translation by the poet Unsuri. The Greek novel as a genre began in the first century CE, and flourished in the first four centuries; it is thus a product of the Roman Empire. The exact relationship between the Greek novel and the Latin novels of Petronius and Apuleius is debated, but both Roman writers are thought by most scholars to have been aware of and to some extent influenced by the Greek novels.

Hippolytus of Rome (/həˈpɑːlɪtəs/ hi-PAH-lit-əs, Ancient Greek: Ἱππόλυτος; Romanized: Hippólytos, c. 170 – c. 235 AD) was a bishop of Rome and one of the most important Christian theologians of the second and third centuries whose provenance, identity, and corpus remain elusive to scholars and historians. Suggested communities include Rome, Palestine, Egypt, Anatolia, and other regions of the Middle East. The best historians of literature in the ancient church, including Eusebius and Jerome, openly admit they cannot name where Hippolytus the biblical commentator and theologian served in leadership. They had read his works but did not possess evidence of his community. Photios I of Constantinople describes him in his Bibliotheca (cod. 121) as a disciple of Irenaeus, who was said to be a disciple of Polycarp; from the context, it seems Photios was suggesting Hippolytus publicly identified himself in this way. But this assertion is doubtful. One older theory claims he came into conflict with the popes of his time and seems to have headed a schismatic group as a rival to the bishop of Rome, thus becoming an antipope. In this view, he opposed the Roman popes because they softened the penitential system to accommodate the large number of new pagan converts. However, he was reconciled to the Church before he died as a martyr.

Starting in the fourth century, various legends arose identifying him as a priest of the Novatianist schism or as a soldier converted by Saint Lawrence. He has also been confused with another martyr of the same name. Pope Pius IV identifies him as "Saint Hippolytus, Bishop of Pontus", martyred in the reign of Severus Alexander, using as a source an inscription on a statue found at the Church of Saint Lawrence in Rome and kept at the Vatican.
